ACETAL METATHESIS POLYMERIZATION

摘要

A method of preparing a polyacetal comprising polymerization of a mixture comprising a plurality of at least one bis-acetal monomer in the presence of an acid catalyst that promotes the metathesis of the acetal units. The bis-acetal can be formed from an acid catalyzed exchange between a mono-acetal monomer with a diol. The formation of the bis- acetal and the polyaeetal can be carried out simultaneously. The diol can be isolated from a biorenewable source and the ultimate polyaeetal is a degradable or biodegradable polymer.
